Polyribosomes
Caption:
Polyribosomes as seen under the electron microscope. They were taken from giant salivary gland cells of the midgefly, Chironomus thummi. Note that the nascent polypeptide chain is apparent as it emerges from each ribosome. Its length increases as translation proceeds from left (5’) to right (3’) along the mRNA. (Photo: E. V.

Investigation of Hemoglobin
Caption:
Investigation of hemoglobin derived from HbAHbA and HbSHbS individuals by using electrophoresis, protein fingerprinting, and amino acid analysis. Hemoglobin from individuals with sickle-cell anemia (HbSHbS) (a) migrates differently in an electrophoretic field, (b) shows an altered peptide in fingerprint analysis, and (c) shows an altered amino acid, valine, at the sixth position in the Beta chain. During electrophoresis, heterozygotes (HbAHbS) reveal both forms of hemoglobin.
